ABSTRACT:
A monolithic bubble ink jet print head includes an anti-curing-deformation part formed at at least one of an inner surface of a nozzle plate or a chamber
ozzle plate forming ink chambers and an outer surface of the nozzle plate or the chamber
ozzle plate forming a front or outer surface of the printer head to prevent an abnormal deformation from being generated in the nozzle plate or the chamber
ozzle plate during a curing process. A fabrication method of a monolithic bubble-ink jet print head includes forming a sacrificial photo resist mold having a flow channel structure including ink chambers and restrictors on the substrate, forming a chamber
ozzle plate having an anti-curing-deformation part and nozzles on the sacrificial photo resist mold, removing the sacrificial photo resist mold from the substrate over which chamber
ozzle plate is formed, and curing the substrate from which the sacrificial photo resist mold is removed.
